Subpart M - Fall Protection
1926.500
(d) Personal fall arrest systems.
Personal fall arrest systems and their
use shall comply with the provisions set forth below. Effective January
1, 1998, body belts are not acceptable as part of a personal fall arrest
system.
Note: The use of a body belt in a positioning
device system is acceptable and is regulated under paragraph (e) of this
section.
(1) Connectors shall be drop forged, pressed
or formed steel, or made of equivalent materials.
(2) Connectors shall have a corrosion-resistant
finish, and all surfaces and edges shall be smooth to prevent damage to
interfacing parts of the system.
(3) Dee-rings and snaphooks shall have
a minimum tensile strength of 5,000 pounds (22.2 kN).
(4) Dee-rings and snaphooks shall be proof-tested
to a minimum tensile load of 3.600 pounds (16 kN) without cracking, breaking,
or taking permanent deformation.
(5) Snaphooks shall be sized to be compatible
with the member to which they are connected to prevent unintentional disengagement
of the snaphook by depression of the snaphook keeper by the connected member,
or shall be a locking type snaphook designed and used to prevent disengagement
of the snaphook by the contact of the snaphook keeper by the connected
member. Effective January 1, 1998, only locking type snaphooks shall be
used.
(6) Unless the snaphook is a locking type
and designed for the following connections, snaphooks shall not be engaged:
(i) Directly to webbing, rope or wire
rope;
(ii) to each other;
(iii) to a dee-ring to which another snaphook
or other connector is attached;
(iv) to a horizontal lifeline; or
(v) to any object which is compatibly
shaped or dimensioned in relation to the snaphook such that unintentional
disengagement could occur by the connected object being able to depress
the snaphook keeper and release itself.
(7) On suspended scaffolds or similar
work platforms with horizontal lifelines which may become vertical lifelines,
the devices used to connect to a horizontal lifeline shall be capable of
locking in both directions on the lifeline.
(8) Horizontal lifelines shall be designed,
installed, and used, under the supervision of a qualified person, as part
of a complete personal fall arrest system, which maintains a safety factor
of at least two.
(9) Lanyards and vertical lifelines shall
have a minimum breaking strength of 5,000 pounds (22.2 kN).
(10)
(i) Except as provided in paragraph (d)(10)(ii)
of this section, when vertical lifelines are used, each employee shall
be attached to a separate lifeline.
(ii) During the construction of elevator
shafts, two employees may be attached to the same lifeline the hoistway,
provided both employees are working atop a false car that is equipped with
guardrails; the strength of the lifeline is 10,000 pounds (5,000 pounds
per employee attached) (44.4 kN); and all other criteria specified in this
paragraph for lifelines have been met.
(11) Lifelines shall be protected against
being cut or abraded.
(12) Self-retracting lifelines and lanyards
which automatically limit free fall distance to 2 feet (0.61 m) or less
shall be capable of sustaining a minimum tensile load of 3,000 pounds (13.3
kN) applied to the device with the lifeline or lanyard in the fully extended
position.
(13) Self-retracting lifelines and lanyards
which do not limit free fall distance to 2 feet (0.61 m) or less, ripstitch
lanyards, and tearing and deforming lanyards shall be capable of sustaining
a minimum tensile load of 5,000 pounds (22.2 kN) applied to the device
with the lifeline or lanyard in the fully extended position.
(14) Ropes and straps (webbing) used in
lanyards, lifelines, and strength components of body belts and body harnesses
shall be made from synthetic fibers.
(15) Anchorages used for attachment of
personal fall arrest equipment shall be independent of any anchorage being
used to support or suspend platforms and capable of supporting at least
5,000 pounds (22.2kN) per employee attached, or shall be designed, installed,
and used as follows:
(i) as part of a complete personal fall
arrest system which maintains a safety factor of at least two; and
(ii) under the supervision of a qualified
person.
(16) Personal fall arrest systems, when
stopping a fall, shall:
(i) limit maximum arresting force on an
employee to 900 pounds ( 4kN) when used with a body belt;
(ii) limit maximum arresting force on
an employee to 1,800 pounds (8 kN) when used with a body harness;
(III) be rigged such that an employee
can neither free fall more than 6 feet (1.8 m), nor contact any lower level;
(iv) bring an employee to a complete stop
and limit maximum deceleration distance an employee travels to 3.5 feet
(1.07 m); and,
(v) have sufficient strength to withstand
twice the potential impact energy of an employee free falling a distance
of 6 feet (1.8 m), or the free fall distance permitted by the system, whichever
is less.
Note: If the personal fall arrest system
meets the criteria and protocols contained in Appendix C to subpart M,
and if the system is being used by an employee having a combined person
and tool weight of less than 310 pounds (140 kg), the system will be considered
to be in compliance with the provisions of paragraph (d)(16) of this section.
If the system is used by an employee having a combined tool and body weight
of 310 pounds (140 kg) or more, then the employer must appropriately modify
the criteria and protocols of the Appendix to provide proper protection
for such heavier weights, or the system will not be deemed to be in compliance
with the requirements of paragraph (d)(16) of this section.
(17) The attachment point of the body
belt shall be located in the center of the wearer's back. The attachment
point of the body harness shall be located in the center of the wearer's
back near shoulder level, or above the wearer's head.
(18) Body belts, harnesses, and components
shall be used only for employee protection (as part of a personal fall
arrest system or positioning device system) and not to hoist materials.
(19) Personal fall arrest systems and
components subjected to impact loading shall be immediately removed from
service and shall not be used again for employee protection until inspected
and determined by a competent person to be undamaged and suitable for reuse.
(20) The employer shall provide for prompt
rescue of employees in the event of a full or shall assure that employees
are able to rescue themselves.
(21) Personal fall arrest systems shall
be inspected prior to each use for wear, damage and other deterioration,
and defective components shall be removed from service.
(22) Body belts shall be at least one
and five-eights (1\5/8\) inches (4.1 cm) wide.
(23) Personal fall arrest systems shall
not be attached to guardrail systems, not shall they be attached to hoists
except as specified in other subparts of this Part.
(24) When a personal fall arrest system
is used at hoist areas, it shall be rigged to allow the movement of the
employee only as far as the edge of the walking/working surface.
